Outstanding bonding. These glues are not the easiest to find, and not cheap. Price for small container is about $20; available through some R.S. Hughes, Graingers, Fastenal, and perhaps other industrial suppliers.

Tip: you can save the added expense of an applicator and dispenser if you're willing to push it out of the unequal cylinders and mix it. Five minute working time.

Hey Ya Going
I used a Devcon product called PLASTIC WELD when I made my sailing rudder and winglet. www.devcon.comIt gets tough like fiberglass when it cures and seems to really make a great bond on Plastics.
I also threw in some high strength adhesive web spray from Aervoe to seal the deal and some pop rivets to lock it up on the leading edge then clamped the rest and let it dry. Works great now ...........kepnutz

Bonds well to a variety of materials G/flex is ideal for bonding a variety of materials, including dissimilar ones. G/flex has a superior grip so that it can be used to bond to metals, plastics, glass, masonry, and fiberglass. G/flex is ideal for repairs to aluminum boats and polyethylene and ABS canoes and kayaks. It can also be used to wet out and bond fiberglass tapes and fabrics.
